This value sets whether GVRP is enabled(2) or disabled(1) on this specific port, effective only when zxr10GvrpGlobalStatus is also enabled device-wide; when disabled here, GVRP packets received on the port are silently discarded and no registrations propagate from other ports, and toggling from disabled to enabled resets this port's GVRP state machines. Admins use it to exclude specific ports, such as those facing untrusted devices, from GVRP dynamic VLAN registration while leaving it active elsewhere. Setting it to disabled(1) on an access port facing end users would prevent that port from participating in dynamic VLAN propagation.
